What this assembly is and who needs it

The Watts 007MIQTS-S is a double check valve assembly built for backflow prevention in plumbing systems. It serves contractors and facility managers who must protect potable water lines from contamination. The unit meets ASSE 1015 and AWWA C-510-89 standards for double check valve applications. Bronze construction provides corrosion resistance in typical water supply conditions.

Installation notes and common pitfalls

Quarter-turn shutoffs allow quick isolation during service or testing. The assembly uses NPT threaded connections sized at 2 inches, so installers must apply appropriate thread sealant and avoid over-tightening to prevent bronze damage. Overall length is 31 1/2 inches and width is 8 3/4 inches; verify clearance before cutting pipe. Horizontal orientation is standard unless local code permits otherwise. Forgetting to flush lines before installation often traps debris that fouls the check discs.

Who this suits and who should look elsewhere

This valve fits projects requiring a 2-inch double check assembly with quarter-turn test cocks and bronze body. It is not for installations that demand a reduced pressure principle device or a smaller pipe diameter. Buyers needing a different connection type or a compact layout should consider other configurations. Systems requiring lead-free certification for drinking water endpoints must verify local code acceptance separately.

Questions about this item

How can I confirm the double check valve assembly is operating correctly after installation?

Verify that water flows freely through the 2 inch NPT connections and that no backflow occurs when downstream pressure exceeds supply pressure, indicating the check mechanisms are sealing as intended.

What components are included with the 007MIQTS-S and what must be sourced separately?

The assembly includes the bronze valve body with quarter-turn test cocks; pipe fittings, thread sealant, and any required mounting hardware are not included and must be purchased separately.

Which version of the 007MIQTS-S should I select for a system requiring ASSE 1015 compliance?

This model meets ASSE 1015 and AWWA C-510-89 standards, so the standard 2 inch NPT bronze version is the correct choice for installations requiring those certifications.
